Abstract

The invention provides a battery pack parallel connection apparatus and a control method thereof. A first switch is connected with a resistor, the other end of the resistor is connected with one end of a quick charging positive switch, and the other end of the quick charging positive switch is used as the positive output end of a first battery pack quick charging connecting-inserting part; a mainpositive switch is connected with the first switch and the two ends of the resistor in parallel; a second switch is connected with the and resistor the two ends of the quick charging positive switch in parallel; a main negative switch is connected with a quick charging negative switch; the other end of the quick charging negative switch is used as the negative output end of the first battery packquick charging connecting-inserting part; one end of a third switch is used as the positive output end of a second battery pack quick charging connecting-inserting part; one end of a fourth switch isused as the negative output end of the second battery pack quick charging connecting-inserting part; and the positive and negative output ends of the first battery pack quick charging connecting-inserting part are connected with the positive and negative output ends of the second battery pack quick charging connecting-inserting part respectively. By virtue of the battery pack parallel connection apparatus and the control method thereof disclosed in the invention, parallel connection of battery packs is realized on the basis of not changing the original topological structure of an electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a battery pack parallel connection device and a control method thereof. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Affected by traditional car driving habits, the requirement for long driving range of electric vehicles has gradually become a mainstream trend. For example, the Tesla Model-S long driving range version has a maximum pure electric driving range of nearly 500 kilometers. 400km electric car. [0003] Electric vehicles provide kinetic energy through the battery pack (Battery Pack) configured on it. At present, electric vehicles have two conflicting problems of range anxie...
